What is the first step in the design of the field regulators for dc motor?
(a) number of sections
(b) shunt field circuit resistance
(c) shunt field resistance
(d) resistance of step
I had been asked this question by my school principal while I was bunking the class.
I want to ask this question from Motor Starters, Calculation of Resistance Steps & Design of Field Regulators in chapter Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines
